(b) Setting the procedure registration
When the initial data processing request flag (RX18) turns on and the remote device station
initialization procedure registration (SB0D) is set, the following data are registered to the
AJ65BT-64DAV.

POINT
(1) If the remote device station initialization procedure registration directive (SB000D)
is turned off after the initial processing, all RY signals that were turned on within the
initial procedure registration turn off. Hence, turn on the "CH.
analog output
enable/disable flag (RYn0, RYn1, RYn2, RYn3)" in the sequence program.
(2) When the initial setting (analog output enable/disable setting (RWwm+4)) has been
changed, the remote device station initialization procedure registration function
cannot be used.
Change the initial setting in the sequence program.
(3) For the case where the remote device station initialization procedure registration
function is not used but a sequence program is used to make setting, refer to the
user's manual of the used master module.
